  2. “rw”= use for both read and write simultaneously
  3. “a”= it used for append the file and can create a new file too.

Question: Explain the concept of *args and ** kwargs.
Answer: *args , It is a special kind of function definition which is used to pass multiple variables as arguments to the function. *args basically used when you are not sure about how many arguments passeds to the function.

# *args syntax:
def fun(*agrs): #here args is a variable you can choose other variable name too instead of args.
for i in args:
print(i)
fun(“hellow”,”world”,”its” ,“an”, “args”,”function”)
# output
hellow
world
its
an
args
function

**kwargs: It is special kind of function in python which allow the user to mass multiple argument in the function. But in **kwargs the argument passes in the function as dictionaries.

# e.g of **kwargs:

def fun(**kwargs):
For k,v in kwargs.items():
Print(str(k) + “value is “+ str(v)
fun(k1=”value 1”,k2=”value 2”,k3=”value 3”)

#output

k1 value is value 1
k2 value is value 2
k3 value is value 3

Question: How the Python interpreter work?
Answer: The Python interpreter consists two things one is compiler and second is a virtual machine. First, the compiler takes your source code and convert it into Byte code. Byte code is simply a lower level code which is platform independent. Then the byte code is fed into the PVM(Python Virtual Machine). The PVM execute the Byte code and give the output.

Question: Explain the .py and .pyc file extension.
Answer: the .py is the file extension of the Python programme, and .pyc is the file extension of the compiled byte code file which is generated by python.

Question: What is an Exception in python?
Answer: Exception can be defined as an event that occur due to incorrect code or input.

Question: What we use to deal with the exception?
Answer: to avoid the exception we can use try/except statement. If any exception occur, the code in try block stop execution and the code in the except block start to run.

# e.g.

try:
i=2
j=0
print(i/j)
except ZeroDivisionError:
print(“error has occurred because of zero division”)

#output

an error has occurred because of zero division

Question: What is raise an exception?
Answer: to raise the exception and terminate the programme we can use raise exception statement.

# e.g.

print(45)
raise ValueError
print(34)
#output

45

ValueError

Question: Write all errors occurred in python.
Answer: Import error: it occurs when import statement fails

IndexError: when indexing of any list fails

NameError: undefined or unknown variable

SyntaxError: when the code is not written properly

TypeError: when an unappropriated variable is call.

ValueError

There are many other exception or error in python. There are several exceptions in the third party libraries.

Question: What is NumPy?
Answer: it is a fundamental package which is basically used for scientific computation with Python.

Question: Give some main features of NumPy.
Answer: 1. It has a powerful N-dimensional array

  1. shophisticatd functions
  2. tools for integrating c/c++ and Fortran code
  3. useful linear algebra, Fourier transform, and random number capabilities.

Question: What is list comprehensions?
Answer: List comprehension is a method which can make the list in a concise way.

#e.g

Lis=[i*I for i in range(10) if i%2==0]

Question: What is the difference between xrange() and range()?
Answer: both range() and xrange() shear the same properties, but the main difference occur in their return type. xrange() return the xrange object but the range return the list object.
